****WARNING****
Fire Suppression Systems
Extreme caution should be exercised when this unit
is installed in applications that are collecting
volatile or potentially flammable contaminates such
as cooking grease and petroleum based oils.
Trion strongly recommends a fire suppression
system be installed in the ductwork and on the
Model 75 in cases where these contaminates are
collected on the cell plates and collect on the
attached ductwork.
Contact the factory for questions or concerns
regarding a fire suppression system.
3. Outdoor Installations
Requirements for outdoor protection vary in accordance
to climate and equipment component arrangement for
the particular job. The best approach, for equipment
protection, is the construction of a heated shed or
building over the installation. As an alternative, the
installing contractor should treat the equipment as
required to meet the specific needs. Detailed
discussions of the Model 75 components are as follows,
using a rooftop installation as an example (refer to
Figure 3):
Adjoining Duct Work (not supplied by Trion)
The ductwork located on the air entering side of the
cabinet, between the point where it enters the roof and
the cabinet, must be air tight to prevent the entrance of
moisture, especially if it is under negative pressure. It
must also be adequately insulated or other means taken
to prevent the formation of condensation through
temperature change. Condensation will short out the
ionizing-collecting cells. Insulation must be of the
outdoor variety.
Trion Model 75 Cabinet
The access doors on the Model 75 cabinet are gasketed
and the unit is basically sealed against air leakage. The
paint finish (epoxy) is for interior and exterior use. Like
the air-entering duct, the cabinet must be insulated or
other means taken to prevent condensation from taking
place, which results in electrical shorting of the ionizing-
collecting cells. Insulation, when employed must be
suitable for outdoor applications and when applied,
consideration given to all access door openings and
electrical interlock box covers.
Controller/PWM Power Supplies
As the controller/power supplies are designed for
remote mounting, they can be, in many cases, located
indoors and still be reasonably close to the main
cabinet. If located outdoors with the cabinet, it must be
weather protected.
Drain Line
The drain line, located under the ionizing/collecting cell
access door at the lowest point of the Trion cabinet
drain pan, should be piped with as short a run as
possible to the heated interior of the building.
Preferably, straight down from the drain pan supply
through the floor. The normally recommended drain line
trap, to seal off the cabinet from the drain against the
system pressure, should be located in the heated
interior. If not installed in this manner, heat wrap or
other means should be employed to prevent freezing.
Clean-outs are recommended to be installed in all drain
lines.
SECTION II INSTALLATION
FOR THE INSTALLING CONTRACTOR
1. Unpack and Inspect
At the time the unit is received, all shipping containers
and their contents should be examined for damage. Any
damage occurring in shipment must be immediately
reported to the carrier, an inspection report completed
and a claim filed at the receiving point.
The unit cabinet is shipped completely assembled and,
where size permits, the ionizing-collecting cells are
shipped inside the cabinet. On large units, the upper tier
of cells may be shipped in separate containers. The
controller, and other separate accessories are shipped
in the containers as noted on the packing list.
2. Position Air Cleaner Cabinet
To reduce weight for ease in handling, remove the pre-
filters, after-filters and the ionizing-collecting cells from
the cabinet, and place them safely aside. Position the
cabinet in the designated location giving consideration
to the following points:
(a) Provide sufficient clearance in front of the access
doors for ionizing-collecting cell and mechanical
filter removal. A minimum of 39 inches is
required. (see figure 5)
(b) Level the cabinet to assure proper drainage from
the drain pan.
(c) Unless specific design features have been
prearranged, the direction of airflow through the
cabinet may be either from the right or the left.
When the ionizing-collecting cells are reinstalled,
the directional arrows on the cell end plates must
concur with airflow through the cabinet. If mist
suppressors have been specified, they are to be
installed on the air entering side of the unit.
After the cabinet has been properly located, it may be
secured into place at the predrilled factory mounting
pads either by bolting or welding.
3. Connect Adjoining Duct Work
Depending on the application, the installation plan may
or may not call for adjoining ductwork on the air entering
and/or air leaving sides of the cabinet.
When adjoining ducting is to be installed, the bottom of
the horizontal duct runs should be relatively flat and
